为适应管弦乐和交响乐演奏的需要,设置了一个10.4米高、38.1吨重的声反射罩。需要时由后台运送到前台。用气垫减少底部磨擦力,进行水平推移锁方法运送,运送—次需要45分钟。这个声罩是拼装式的,可大可小,演奏交响乐时可以加到最大。同时,根据各种演出的需要,舞台、升降式乐池、观众厅三者之间可以作相互调整,使座位数在1690至1815间变化。包箱后方的花格板内是声反射装置,板后夹层设可升降的吸音板,用调节吸音板遮挡面积的方法,改
In order to meet the needs of orchestra and symphony performances, a 10.4-meter high, 38.1-ton acoustic reflector was set up. Ship from the background to the front desk when needed. The air cushion is used to reduce the bottom friction force and carry out the level-elevation lock method. The delivery takes 45 minutes. The mask is a combination of sizes, ranging from maximum to maximum when playing symphony.
